Galactic Subsystems on the Basis of Cumulative Distribution of Space Velocities

Blog Article

A sample containing $4,614$ stars with available space velocities and high-quality kinematical data from the Arihip Catalogue is formed.For the purpose of distinguishing galactic subsystems the cumulative distribution of space velocities is studied.The pride sundancer scooter fractions of the three subsystems are found to be: thin disc 92%, thick disc 6% and halo 2%.These results are verified by analysing the elements of velocity ellipsoids and the shape and size of the galactocentric ford tridon orbits of the sample stars, i.

e.the planar and vertical eccentricities of the orbits.
